4.4 Performance characteristics Drive performance is characterized by the following parameters:
Command Overhead
Mechanical Positioning
Seek Time
Latency
Data Transfer Speed
Buffering Operation (Look ahead/Write Cache)
Note: All the above parameters contribute to drive performance. There are other parameters which contribute to the performance of the actual system. This specification defines the essential characteristics of the drive. This specification does not include the system throughput as this is dependent upon the system and the application. Drive performance may suffer if the host writes data starting or ending on an LBA that is misaligned with respect to the physical sector boundaries
The following table gives a typical value for each parameter.

Typical and Max. are defined throughout the performance specification as follows:
Typical Average of the drive population tested at nominal environmental and voltage conditions. Max. Maximum value measured on any one drive over the full range of the environmental and
voltage conditions. (See section 6.1, "Environment" and section 6.2, "DC power requirements" )
The seek time is measured from the start of motion of the actuator to the start of a reliable read or write operation. A reliable read or write operation implies that error correction/recovery is not employed to correct arrival problems. The Average Seek Time is measured as the weighted average of all possible seek combinations.
max. (max. + 1 – n)(Tnin + Tnout) n=1 Weighted Average = –––––––––––––––––––––––––––– (max. + 1)(max) Where: max. = maximum seek length n = seek length (1-to-max.) Tnin = inward measured seek time for an n-track seek Tnout = outward measured seek time for an n-track seek

Spin-Up Start up time period from spindle stop or power down.
Seek Seek operation mode
Write Write operation mode
Read Read operation mode
Performance idle
The device is capable of responding immediately to media access requests. All electronic components remain powered and the full frequency servo remains operational.
Active idle
The device is capable of responding immediately to media access requests. Some circuitry—including servo system and R/W electronics—is in power saving mode. The head is parked near the mid-diameter the disk without track-following. A device in Active idle mode may take longer to complete the execution of a command because it must activate that circuitry.
Low power idle The head is unloaded onto the ramp position. The spindle motor rotates at product target speed.
Standby The device interface is capable of accepting commands. The spindle motor is stopped. All circuitry but the host interface is in power saving mode. The execution of commands is delayed until the spindle becomes ready.
Sleep The device requires a soft reset or a hard reset to be activated. All electronics, including spindle motor and host interface, are shut off.

5K1500 OEM Specification
5 Data integrity 5.1 Data loss on power off Data loss will not be caused by a power off during any operation except the write operation.
A power off during a write operation causes the loss of any received or resident data that has not been written onto the disk media.
A power off during a write operation might make a maximum of one sector of data unreadable. This state can be recovered by a rewrite operation.
5.2 Write Cache When the write cache is enabled, the write command may complete before the actual disk write operation finishes. This means that a power off, even after the write command completion, could cause the loss of data that the drive has received but not yet written onto the disk.
In order to prevent this data loss, confirm the completion of the actual write operation prior to the power off by issuing a
Soft reset
Hard reset
Flush Cache command
Standby command
Standby Immediate command
Sleep command
Confirm the command’s completion.
5.3 Equipment status The equipment status is available to the host system any time the drive is not ready to read, write, or seek. This status normally exists at the power-on time and will be maintained until the following conditions are satisfied:
The access recalibration/tuning is complete.
The spindle speed meets the requirements for reliable operation.
The self-check of the drive is complete.
The appropriate error status is made available to the host system if any of the following conditions occur after the drive has become ready:
The spindle speed lies outside the requirements for reliable operation.
The occurrence of a Write Fault condition.
5.4 WRITE safety The drive ensures that the data is written into the disk media properly. The following conditions are monitored during a write operation. When one of these conditions exceeds the criteria, the write operation is terminated and the automatic retry sequence is invoked.
Head off track
External shock
Low supply voltage
Spindle speed out of tolerance
Head open/short
21
5K1500 OEM Specification
5.5 Data buffer test The data buffer is tested at power on reset and when a drive self-test is requested by the host. The test consists of a write/read '00'x and 'ff'x pattern on all buffers.
5.6 Error recovery Errors occurring on the drive are handled by the error recovery procedure.
Errors that are uncorrectable after application of the error recovery procedure are reported to the host system as non-recoverable errors.
5.7 Automatic reallocation The sectors that show some errors may be reallocated automatically when specific conditions are met. The drive does not report any auto reallocation to the host system. The conditions for auto reallocation are described below.
5.7.1 Non-recovered write errors
When a write operation cannot be completed after the Error Recovery Procedure (ERP) is fully carried out, the sectors are reallocated to the spare location. An error is reported to the host system only when the write cache is disabled and the auto reallocation has failed.
5.7.2 Non-recoverable read error
When a read operation fails after ERP is fully carried out, a hard error is reported to the host system. This location is registered internally as a candidate for the reallocation. When a registered location is specified as a target of a write operation, a sequence of media verification is performed automatically. When the result of this verification meets the required criteria, this sector is reallocated.
5.7.3 Recovered read errors
When a read operation for a sector fails and is recovered at the specific ERP step, the sector is reallocated automatically. A media verification sequence may be run prior to the reallocation according to the predefined conditions.

6.3 Reliability 6.3.1 Data reliability
Probability of not recovering data is 1 in 1014 bits read
LDPC implementation
Offline erasure correction performed recovers up to 3320 bits of errors in 1 sector.
6.3.2 Failure prediction (S.M.A.R.T.)
The drive supports Self-monitoring, analysis and reporting technology (S.M.A.R.T.) function. The details are described in section 12.8, "S.M.A.R.T. Function" and in Section 14.41, "S.M.A.R.T. Function Set (B0h)"
6.3.3 Cable noise interference
To avoid any degradation of performance throughput or error when the interface cable is routed on top or comes in contact with the HDA assembly, the drive must be grounded electrically to the system frame by four screws. The common mode noise or voltage level difference between the system frame and power cable ground or AT interface cable ground should be in the allowable level specified in the power requirement section.
6.3.4 Service life and usage condition
The drive is designed to be used under the following conditions:
The drive should be operated within specifications of shock, vibration, temperature, humidity, altitude, and magnetic field.
The drive should be protected from ESD.
The breathing hole in the top cover of the drive should not be covered.
Force should not be applied to the cover of the drive.
The specified power requirements of the drive should be satisfied.
The drive frame should be grounded electrically to the system through four screws.
The drive should be mounted with the recommended screw depth and torque.
The interface physical and electrical requirements of the drive should satisfy Serial ATA Revision 3.0.
The power-off sequence of the drive should comply with the 6.3.6.2,"Required power-off sequence.”
Service life of the drive is approximately 5 years or 20,000 power on hours, whichever comes first, under the following assumptions:
Less than 333 power on hours per month.
Seeking/Writing/Reading operation is less than 20% of power on hours.
This does not represent any warranty or warranty period. Applicable warranty and warranty period are covered by the purchase agreement.
6.3.5 Preventive maintenance
None.
26
5K1500 OEM Specification
6.3.6 Load/unload
The product supports a minimum of 600,000 normal load/unloads.
Load/unload is a functional mechanism of the hard disk drive. It is controlled by the drive micro code. Specifically, unloading of the heads is invoked by the following commands:
Standby
Standby immediate
Sleep
Load/unload is also invoked as one of the idle modes of the drive.
The specified start/stop life of the product assumes that load/unload is operated normally, not in emergency mode.
6.3.6.1 Emergency unload When hard disk drive power is interrupted while the heads are still loaded the micro code cannot operate and the normal 5-volt power is unavailable to unload the heads. In this case, normal unload is not possible. The heads are unloaded by routing the back EMF of the spinning motor to the voice coil. The actuator velocity is greater than the normal case and the unload process is inherently less controllable without a normal seek current profile.
Emergency unload is intended to be invoked in rare situations. Because this operation is inherently uncontrolled, it is more mechanically stressful than a normal unload.
The drive supports a minimum of 20,000 emergency unloads.
6.3.6.2 Required Power-Off Sequence The required host system sequence for removing power from the drive is as follows:
Step 1: Issue one of the following commands.
Standby
Standby immediate
Sleep
Note: Do not use the Flush Cache command for the power off sequence because this command does not invoke Unload.
Step 2: Wait until the Command Complete status is returned.
The host system time out value needs to be 30 seconds considering error recovery time.
Step 3: Terminate power to HDD.
This power-down sequence should be followed for entry into any system power-down state, system suspend state, or system hibernation state. In a robustly designed system, emergency unload is limited to rare scenarios, such as battery removal during operation.
6.3.6.3 Power switch design considerations In systems that use the Travelstar 5K1500 consideration should be given to the design of the system power switch.
HGST recommends that the switch operate under control of the host system, as opposed to being hardwired. The same recommendation is made for cover-close switches. When a hardwired switch is turned off, emergency unload occurs, as well as the problems cited in section 5.1, "Data loss by power off" and section 5.2, “Write Cache”.
27
5K1500 OEM Specification
6.3.6.4 Test considerations Start/stop testing is classically performed to verify head/disk durability. The heads do not land on the disk, so this type of test should be viewed as a test of the load/unload function.
Start/Stop testing should be done by commands through the interface, not by power cycling the drive. Simple power cycling of the drive invokes the emergency unload mechanism and subjects the HDD to non-typical mechanical stress.
Power cycling testing may be required to test the boot-up function of the system. In this case HGST recommends that the power-off portion of the cycle contain the sequence specified in section 6.3.6.2, "Required Power-Off Sequence”. If this is not done, the emergency unload function is invoked and non-typical stress results.

6.4.4 Mounting orientation
The drive will operate in all axes (six directions). Performance and error rate will stay within specification limits if the drive is operated in the other permissible orientations from which it was formatted. Thus a drive formatted in a horizontal orientation will be able to run vertically and vice versa.
The recommended mounting screw torque is 0.3±0.05 Nm.
The recommended mounting screw depth is 3.0±0.3 mm for bottom and 3.5±0.5 mm for horizontal mounting.
The user is responsible for using the appropriate screws or equivalent mounting hardware to mount the drive securely enough to prevent excessive motion or vibration of the drive at seek operation or spindle rotation.
6.4.5 Load/unload mechanism
The head load/unload mechanism is provided to protect the disk data during shipping, movement, or storage. Upon power down, a head unload mechanism secures the heads at the unload position. See section 6.5.4, "Non-operating shock" for additional details.

Operating mode: Continuous random cylinder selection and seek operation of the actuator with a dwell time at each cylinder. The seek rate for the drive can be calculated as shown below.
Ns = 0.4/(Tt + T1)
where:
Ns = average seek rate in seeks/s
Tt = published seek time from one random track to another without including rotational latency
T1= equivalent time in seconds for the drive to rotate by half a revolution
6.6.2 Discrete tone penalty
Discrete tone penalties are added to the A-weighted sound power (Lw) with the following formula only when determining compliance.
Lwt(spec) = Lw = 0.1Pt + 0.3 < 4.0 (Bels)
where
Lw = A-weighted sound power level
Pt = Value of desecrate tone penalty = dLt – 6.0(dBA)

11 Registers In Serial ATA, the host adapter contains a set of registers that shadow the contents of the traditional device registers, referred to as the Shadow Register Block. Shadow Register Block registers are interface registers used for delivering commands to the device or posting status from the device. About details, please refer to the Serial ATA Specification.
In the following cases, the host adapter sets the BSY bit in its shadow Status Register and transmits a FIS to the device containing the new contents.
Command register is written in the Shadow Register Block Device Control register is written in the Shadow Register Block with a change of state of the SRST bit COMRESET is requested
11.1 Register naming convention This specification uses the same naming conventions for the Command Block Registers as the ATA8-ACS standard. However, the register naming convention is different from that uses in the Serial ATA 3.0 specification. The following table defines the corresponding of the register names used in this specification with those used in the Serial ATA 3.0 specification.

5K1500 OEM Specification
12.3 Power-off considerations 12.3.1 Load/Unload
Load/Unload is a functional mechanism of the HDD. It is controlled by the drive microcode. Specifically, unloading of the heads is invoked by the commands:
Command Response Standby UL -> Comp. Standby immediate UL -> Comp. Sleep UL -> Comp.
“UL” means “unload”. “Comp” means “complete”.
Table 33 Device’s behavior by ATA commands
Load/unload is also invoked as one of the idle modes of the drive.
The specified start/stop life of the product assumes that load/unload is operated normally, NOT in emergency mode.
12.3.2 Emergency unload
When HDD power is interrupted while the heads are still loaded, the microcode cannot operate and the normal 5V power is unavailable to unload the heads. In this case, normal unload is not possible, so the heads are unloaded by routing the back-EMF of the spinning motor to the voice coil. The actuator velocity is greater than the normal case, and the unload process is inherently less controllable without a normal seek current profile.
Emergency unload is intended to be invoked in rare situations. Because this operation is inherently uncontrolled, it is more mechanically stressful than a normal unload.
A single emergency unload operation is more stressful than 100 normal unloads. Use of emergency unload reduces the start/stop life of the HDD at a rate at least 100X faster than that of normal unload, and may damage the HDD.
12.3.3 Required power-off sequence
Problems can occur on most HDDs when power is removed at an arbitrary time. Examples:
Data loss from the write buffer. If the drive is writing a sector, the sector contents are destroyed and reading that sector results in a
hard error. You may then turn off the HDD in the following order:
1. Issue Standby, Standby Immediate or sleep command. 2. Wait until COMMAND COMPLETE STATUS is returned. 3. Terminate power to HDD.
This power-down sequence should be followed for entry into any system power-down state, or system suspend state, or system hibernation state. In a robustly designed system, emergency unload is limited to rare scenarios such as battery removal during operation.

5K1500 OEM Specification
12.4 Sector Addressing Mode All addressing of data sectors recorded on the device’s media is by a logical sector address. The logical CHS address for HTS5415XXA9X6XX is different from the actual physical CHS location of the data sector on the disk media.
HTS5415XXA9X6XX support both Logical CHS Addressing Mode and LBA Addressing Mode as the sector addressing mode.
The host system may select either the currently selected CHS translation addressing or LBA addressing on a command-by-command basis by using the L bit in the DEVICE register. So a host system must set the L bit to 1 if the host uses LBA Addressing mode.
12.4.1 Logical CHS Addressing Mode
The logical CHS addressing is made up of three fields: the cylinder number, the head number and the sector number. Sectors are numbered from 1 to the maximum value allowed by the current CHS translation mode but can not exceed 255(0Ffh). Heads are numbered from 0 to the maximum value allowed by the current CHS translation mode but can not exceed 15(0fh). Cylinders are numbered from 0 to the maximum value allowed by the current CHS translation mode but cannot exceed 65535(0FFFfh).
When the host selects a CHS translation mode using the INITIALIZE DEVICE PARAMETERS command, the host requests the number of sectors per logical track and the number of heads per logical cylinder. The device then computes the number of logical cylinders available in requested mode.
The default CHS translation mode is described in the Identify Device Information. The current CHS translation mode also is described in the Identify Device Information.
12.4.2 LBA Addressing Mode
Logical sectors on the device shall be linearly mapped with the first LBA addressed sector (sector 0) being the same sector as the first logical CHS addressed sector ( cylinder 0, head 0, sector 1). Irrespective of the logical CHS translation mode currently in effect, the LBA address of a given logical sector does not change. The following is always true:
LBA = ( (cylinder * heads_per_cylinder + heads) * sectors_per_track ) + sector - 1
where heads_per_cylinder and sectors_per_track are the current translation mode values.
On LBA addressing mode, the LBA value is set to the following register.
Device <--- LBA bits 27-24 LBA High <--- LBA bits 23-16 LBA Mid <--- LBA bits 15- 8 LBA Low <--- LBA bits 7- 0

5K1500 OEM Specification
12.5 Power Management Feature The power management feature set permits a host to modify the behavior in a manner which reduces the power required to operate. The power management feature set provides a set of commands and a timer that enables a device to implement low power consumption modes.
HTS5415XXA9X6XX implements the following set of functions.
1. A Standby timer 2. Idle command 3. Idle Immediate command 4. Sleep command 5. Standby command 6. Standby Immediate command
12.5.1 Power Mode
Sleep Mode The lowest power consumption when the device is powered on occurs in Sleep Mode. When in sleep mode, the device requires a reset to be activated.
Standby Mode The device interface is capable of accepting commands, but as the media may not immediately accessible, there is a delay while waiting for the spindle to reach operating speed.
Idle Mode Refer to the section of Adaptive Battery Life Extender Feature. Active Mode The device is in execution of a command or accessing the disk media with read
look-ahead function or write cache function.
12.5.2 Power Management Commands
The Check Power Mode command allows a host to determine if a device is currently in, going to or leaving standby mode.
The Idle and Idle Immediate commands move a device to idle mode immediately from the active or standby modes. The idle command also sets the standby timer count and starts the standby timer.
The sleep command moves a device to sleep mode. The device’s interface becomes inactive at the completion of the sleep command. A reset is required to move a device out of sleep mode. When a device exits sleep mode it will enter standby mode.
The Standby and Standby Immediate commands move a device to standby mode immediately from the active or idle modes. The standby command also sets the standby timer count.
12.5.3 Standby/Sleep command completion timing
1. Confirm the completion of writing cached data in the buffer to media 2. Unload heads on the ramp 3. Set DRDY bit and DSC bit in Status Register 4. Activate the spindle break to stop the spindle motor 5. Wait until spindle motor is stopped 6. Perform post process
12.5.4 Status
In the active, idle and standby modes, the device shall have RDY bit of the status register set. If BSY bit is not set, device shall be ready to accept any command.
In sleep mode, the device’s interface is not active. A host shall not attempt to read the device’s status or issue commands to the device.
49
5K1500 OEM Specification
12.5.5 Interface Capability for Power Modes
Each power mode affects the physical interface as defined in the following table:
Mode BSY RDY Interface active Media Active x x Yes Active Idle 0 1 Yes Active Standby 0 1 Yes Inactive Sleep x x No Inactive
Table 34 Power conditions
Ready (RDY) is not a power condition. A device may post ready at the interface even though the media may not be accessible.
12.5.6 Initial Power Mode at Power On
After power on the device goes to IDLE mode or STANDBY mode depending on the setting of the Power Up in Standby Feature set

5K1500 OEM Specification
12.6 Advanced Power Management (Adaptive Battery Life Extender 3) Feature
This feature provides power saving without performance degradation. The Adaptive Battery Life Extender 3 (ABLE-3) technology intelligently manages transition among power modes within the device by monitoring access patterns of the host.
This technology has three idle modes; Performance Idle mode, Active Idle mode, and Low Power Idle mode.
This feature allows the host to select an advanced power management level. The advanced power management level is a scale from the lowest power consumption setting of 01h to the maximum performance level of Feh. Device performance may increase with increasing advanced power management levels. Device power consumption may increase with increasing advanced power management levels. The advanced power management levels contain discrete bands, described in the section of Set Feature command in detail.
This feature set uses the following functions:
A SET FEATURES subcommand to enable Advanced Power Management A SET FEATURES subcommand to disable Advanced Power Management
The Advanced Power Management feature is independent of the Standby timer setting. If both Advanced Power Management level and the Standby timer are set, the device will go to the Standby state when the timer times out or the device’s Advanced Power Management algorithm indicates that it is time to enter the Standby state.
The IDENTIFY DEVICE response word 83, bit 3 indicates that Advanced Power Management feature is supported if set. Word 86, bit 3 indicates that Advanced Power Management is enabled if set.
Word 91, bits 7-0 contain the current Advanced Power Management level if Advanced Power Management is enabled.
12.6.1 Performance Idle mode
This mode is usually entered immediately after Active mode command processing is complete, instead of conventional idle mode. In Performance Idle mode, all electronic components remain powered and full frequency servo remains operational. This provides instantaneous response to the next command. The duration of this mode is intelligently managed as described below.
12.6.2 Active Idle mode
In this mode, power consumption is 45-55% less than that of Performance Idle mode. Additional electronics are powered off, and the head is parked near the mid-diameter of the disk without servoing. Recovery time to Active mode is about 20ms.
12.6.3 Low Power Idle mode
Power consumption is 60%-65% less than that of Performance Idle mode. The heads are unloaded on the ramp, however the spindle is still rotated at the full speed. Recovery time to Active mode is about 300ms.
12.6.4 Transition Time
The transition time is dynamically managed by users recent access pattern, instead of fixed times. The ABLE-3 algorithm monitors the interval between commands instead of the command frequency of ABLE-2. The algorithm supposes that next command will come with the same command interval distribution as the previous access pattern. The algorithm calculates the expected average saving energy and response delay for next command in several transition time case based on this assumption. And it selects the most effective transition time with the condition that the calculated response delay is shorter than the value calculated from the specified level by Set Feature Enable Advanced Power Management command.
The optimal time to enter Active Idle mode is variable depending on the users recent behavior. It is not possible to achieve the same level of Power savings with a fixed entry time into Active Idle because every users data and access pattern is different. The optimum entry time changes over time.
The same algorithm works for entering into Low Power Idle mode and Standby mode, which consumes less power but need more recovery time switching from this mode to Active mode.

12.7 Interface Power Management Mode (Slumber and Partial)

12.8 S.M.A.R.T. Function The intent of Self-monitoring, analysis and reporting technology (S.M.A.R.T) is to protect user data and prevent unscheduled system downtime that may be caused by predictable degradation and/or fault of the device. By monitoring and storing critical performance and calibration parameters, S.M.A.R.T devices employ sophisticated data analysis algorithms to predict the likelihood of near-term degradation or fault condition. By alerting the host system of a negative reliability status condition, the host system can warn the user of the impending risk of a data loss and advise the user of appropriate action.
Since S.M.A.R.T. utilizes the internal device microprocessor and other device resources, there may be some small overhead associated with its operation. However, special care has been taken in the design of the S.M.A.R.T. algorithms to minimize the impact to host system performance. Actual impact of S.M.A.R.T. overhead is dependent on the specific device design and the usage patterns of the host system. To further ensure minimal impact to the user, S.M.A.R.T. capable devices are shipped from the device manufacturer’s factory with the S.M.A.R.T. feature disabled. S.M.A.R.T. capable devices can be enabled by the system OEMs at time of system integration or in the field by aftermarket products.
12.8.1 Attributes
Attributes are the specific performance or calibration parameters that are used in analyzing the status of the device. Attributes are selected by the device manufacturer based on that attribute’s ability to contribute to the prediction of degrading or faulty conditions for that particular device. The specific set of attributes being used and the identity of these attributes is vendor specific and proprietary.
12.8.2 Attribute values
Attribute values are used to represent the relative reliability of individual performance or calibration attributes. Higher attribute values indicate that the analysis algorithms being used by the device are predicting a lower probability of a degrading or fault condition existing. Accordingly, lower attribute values indicate that the analysis algorithms being used by the device are predicting a higher probability of a degrading or fault condition existing. There is no implied linear reliability relationship corresponding to the numerical relationship between different attribute values for any particular attribute.
12.8.3 Attribute thresholds
Each attribute value has a corresponding attribute threshold limit which is used for direct comparison to the attribute value to indicate the existence of a degrading or faulty condition. The numerical value of the attribute thresholds are determined by the device manufacturer through design and reliability testing and analysis. Each attribute threshold represents the lowest limit to which its corresponding attribute value can be equal while still retaining a positive reliability status. Attribute thresholds are set at the device manufacturer’s factory and cannot be changed in the field. The valid range for attribute thresholds is from 1 through 253 decimal.
12.8.4 Threshold exceeded condition
If one or more attribute values are less than or equal to their corresponding attribute thresholds, then the device reliability status is negative, indicating an impending degrading or faulty condition.
12.8.5 S.M.A.R.T. commands
The S.M.A.R.T. commands provide access to attribute values, attribute thresholds and other logging and reporting information.
12.8.6 S.M.A.R.T operation with power management modes
The device saves attribute values automatically on every head unload timing except the emergency unload, even if the attribute auto save feature is not enabled. The head unload is done not only by Standby, Standby Immediate, or Sleep command, but also by the automatic power saving functions like ABLE-3 or Standby timer. So basically it is not necessary for a host system to enable the attribute auto save feature, when it utilizes the power management. If the attribute auto save feature is enabled, attribute values will be saved after 30minutes passed since the last saving, besides above condition.

Device Unlocked mode The device enables all commands. If a password is not set this mode is entered after power on, otherwise it is entered by a security unlock or a security erase unit command.
Device Frozen mode The device enables all commands except those which can update the device lock function, set/change password. The device enters this mode via a Security Freeze Lock command. It cannot quit this mode until power off.
12.9.2 Security Level
Following security levels are provided.
High level security When the device lock function is enabled and the User Password is forgotten the device can be unlocked via a Master Password.
Maximum level security When the device lock function is enabled and the User Password is forgotten then only the Master Password with a Security Erase Unit command can unlock the device. Then user data is erased.

5K1500 OEM Specification
12.9.3 Password
This function can have 2 types of passwords as described below.
Master Password When the Master Password is set, the device does NOT enable the Device Lock Function, and the device can NOT be locked with the Master Password, but the Master Password can be used for unlocking the device locked.
User Password The User Password should be given or changed by a system user. When the User Password is set, the device enables the Device Lock Function, and then the device is locked on next power on reset. If Software Setting Preservation is disabled, the device is locked on COMRESET as well.
The system manufacturer/dealer who intends to enable the device lock function for the end users, must set the master password even if only single level password protection is required. Otherwise, if the User Password is forgotten then no one can unlock the device which is locked with the User Password.
12.9.4 Master Password Revision Code
This Master Password Revision Code is set by Security Set Password command with the master password. And this revision code field is returned in the Identify Device command word 92. The valid revision codes are 0001h to FFFeh. The default value of Master Password Revision Code is FFFeh.
Value 0000h and FFFfh is reserved.
12.9.5 Operation example
12.9.5.1 Master Password setting The system manufacturer/dealer can set a initial Master Password using the Security Set Password command, without enabling the Device Lock Function.
12.9.5.2 User Password setting When a User Password is set, the device will automatically enter lock mode the next time the device is powered on.

5K1500 OEM Specification
12.9.5.4 User Password Lost If the User Password is forgotten and High level security is set, the system user can’t access any data. However the device can be unlocked using the Master Password.
If a system user forgets the User Password and Maximum security level is set, data access is impossible. However the device can be unlocked using the Security Erase Unit command to unlock the device and erase all user data with the Master Password.
Figure 7 Password Lost
12.9.5.5 Attempt limit for SECURITY UNLOCK command The SECURITY UNLOCK command has an attempt limit. The purpose of this attempt limit is to prevent that someone attempts to unlock the drive by using various passwords many times.
The device counts the password mismatch. If the password does not match, the device counts it up without distinguishing the Master password and the User password. If the count reaches 5, EXPIRE bit(bit 4) of Word 128 in Identify Device information is set, and then SECURITY ERASE UNIT command and SECURITY UNLOCK command are aborted until a power off. The count and EXPIRE bit are cleared after a power on reset.

12.10 Protected Area Function Protected Area Function is to provide the ‘protected area’ which can not be accessed via conventional method. This ‘protected area’ is used to contain critical system data such as BIOS or system management information. The contents of entire system main memory may also be dumped into ‘protected area’ to resume after system power off.
The LBA/CYL changed by following command affects the Identify Device Information.
Two commands are defined for this function.
Read Native Max Address (‘F8’h) Set Max Address (‘F9’h)
Four security extension commands are implemented as sub-functions of the Set Max Address.
Set Max Set Password Set Max Lock Set Max Freeze Lock Set Max Unlock
12.10.1 Example for operation (In LBA mode)
Assumptions :
For better understanding, the following example uses actual values for LBA, size, etc. Since it is just an example, these values could be different.
Device characteristics
Capacity (native) : 536,870,912 byte (536MB) Max LBA (native) : 1,048,575 (0FFFFfh) Required size for protected area : 8,388,608 byte Required blocks for protected area : 16,384 (004000h) Customer usable device size : 528,482,304 byte (528MB) Customer usable sector count : 1,032,192 (0FC000h) LBA range for protected area : 0FC000h to 0FFFFfh
Shipping HDDs from HDD manufacturer
When the HDDs are shipped from HDD manufacturer, the device has been tested to have a capacity of 536MB,flagging the media defects not to be visible by system.
1. Preparing HDDs at system manufacturer
Special utility software is required to define the size of protected area and store the data into it.
The sequence is :
Issue Read Native Max Address command to get the real device max of LBA/CYL. Returned value shows that native device Max LBA is 0FFFFfh regardless to the current setting.
Make entire device be accessible including the protected area by setting device Max LBA as 0FFFFfh via Set Max Address command. The option could be either nonvolatile or volatile.
Test the sectors for protected area (LBA >= 0FC000h) if required.
Write information data such as BIOS code within the protected area.
Change maximum LBA using Set Max Address command to 0FBFFfh with nonvolatile option.
From this point, the protected area cannot be accessed until next Set Max Address command is issued. Any BIOSes, device drivers, or application software access the HDD as if that is the 528MB device because the device acts exactly same as real 528MB device does.
2. Conventional usage without system software support Since the HDD works as 528MB device, there is no special care to use this device for normal use.
60
5K1500 OEM Specification
3. Advanced usage using protected area The data in the protected area is accessed by following.
Issue Read Native Max Address command to get the real device max LBA/CYL. Returned value shows that native device Max LBA is 0FFFFfh regardless of the current setting.
Make entire device be accessible including the protected area by setting device Max LBA as 0FFFFfh via Set Max Address command with volatile option. By using this option, unexpected power removal or reset will not make the protected area remained accessible.
Read information data from protected area.
Issue POR to inhibit any access to the protected area.
12.10.2 Set Max security extension commands
The Set Max Set Password command allows the host to define the password to be used during the current power on cycle. This password is not related to the password used for the Security Mode Feature set. When the password is set the device is in the Set Max Unlocked mode.
This command requests a transfer of a single sector of data from the host. The table shown below defines the content of this sector of information. The password is retained by the device until the next power cycle. When the device accepts this command the device is in Set Max Unlocked mode.
Word Content 0 Reserved
1-16 Password (32 bytes) 17-255 Reserved
Table 37 Set Max Set Password data content
The Set Max Lock command allows the host to disable the Set Max commands (except Set Max Unlock and Set Max Freeze Lock) until the next power cycle or the issuance and acceptance of the Set Max Unlock command. When this command is accepted the device is in the Set Max Locked mode.
The Set Max Unlock command changes the device from the Set Max Locked mode to the Set Max Unlocked mode.
This command requests a transfer of a single sector of data from the host. The Table shown above defines the content of this sector of information. The password supplied in the sector of data transferred is compared with the stored Set Max password. If the password compare fails, then the device returns command aborted and decrements the unlock counter. On the acceptance of the Set Max Lock command, this counter is set to a value of five and is decremented for each password mismatch when Set Max Unlock is issued and the device is locked. When this counter reaches zero, then the Set Max Unlock command returns command aborted until a power cycle.
The Set Max Freeze Lock command allows the host to disable the SET Max commands (including Set Max Unlock) until the next power cycle. When this command is accepted the device is in the Set Max Frozen mode.
The password, the Set Max security mode and the unlock counter don’t persist over a power cycle but does persist over a COMRESET or software reset.
Note that If this command is immediately preceded by a Read Native Max Address command regardless of Feature register value, it shall be interpreted as a Set Max Address command.
61
5K1500 OEM Specification
12.11 Write Cache Function Write cache is a performance enhancement whereby the device reports completion of the write command (Write Sector(s) and Write Multiple) to the host as soon as the device has received all of the data into its buffer. The device assumes responsibility to write the data subsequently onto the disk.
While writing data after completed acknowledgment of a write command, soft reset or COMRESET does not affect its operation. But power off terminates writing operation immediately and unwritten data are to be lost.
Flush cache, Soft reset, Standby, Standby Immediate and Sleep are executed after the completion of writing to disk media on enabling write cache function. So the host system can confirm the completion of write cache operation by issuing flush cache command, Soft reset, Standby command, Standby Immediate command or Sleep command, and then, by confirming its completion.
12.12 Reassign Function The reassign function is used with read commands and write commands. The sectors of data for reassignment are prepared as the spare data sector. The one entry can register up to 256 (512 byte/sector format) or 32 (4KB sector format) consecutive physical sectors maximally.
This reassignment information is registered internally, and the information is available right after completing the reassign function. Also the information is used on the next power on reset.
If the number of the spare sector reaches 0 sector, the reassign function will be disabled automatically.
The spare tracks for reassignment are located at regular intervals from Cylinder 0. As a result of reassignment, the physical location of logically sequenced sectors will be dispersed.
12.12.1 Auto Reassign Function
The sectors that show some errors may be reallocated automatically when specific conditions are met. The spare tracks for reallocation are located at regular intervals from Cylinder 0. The conditions for auto-reallocation are described below.
Non recovered write errors When a write operation can not be completed after the Error Recovery Procedure(ERP) is fully carried out, the sector(s) are reallocated to the spare location. An error is reported to the host system only when the write cache is disabled and the auto reallocation fails.
If the number of available spare sectors reaches 16 sectors, the write cache function will be disabled automatically.
Non recovered read errors When a read operation fails after defined ERP is fully carried out, a hard error is reported to the host system. This location is registered internally as a candidate for the reallocation. When a registered location is specified as a target of a write operation, a sequence of media verification is performed automatically. When the result of this verification meets the criteria, this sector is reallocated.
Recovered read errors When a read operation for a sector failed once then recovered at the specific ERP step, this sector of data is reallocated automatically. A media verification sequence may be run prior to the relocation according to the pre-defined conditions.

5K1500 OEM Specification
12.13 48-bit Address Feature Set The 48-bit Address feature set allows devices with capacities up to 281,474,976,710,655 sectors. This allows device capacity up to 144,115,188,075,855,360 bytes. In addition, the number of sectors that may be transferred by a single command are increased by increasing the allowable sector count to 16 bits.
Commands unique to the 48-bit Address feature set are:
Flush Cache Ext Read DMA Ext Read Multiple Ext Read Native Max Address Ext Read Sector(s) Ext Read Verify Sector(s) Ext Set Max Address Ext Write DMA Ext Write Multiple Ext Write Sector(s) Ext
The 48-bit Address feature set operates in LBA addressing only. Devices also implement commands using 28-bit addressing, and 28-bit and 48-bit commands may be intermixed.
Support of the 48-bit Address feature set is indicated in the Identify Device response bit 10 word 83. In addition, the maximum user LBA address accessible by 48-bit addressable commands is contained in Identify Device response words 100 through 103.
When the 48-bit Address feature set is implemented, the native maximum address is the value returned by a Read Native Max Address Ext command. If the native maximum address is equal to or less than 268,435,455, a Read Native Max Address shall return the native maximum address. If the native maximum address is greater than 268,435,455, a Read Native Max Address shall return a value of 268,435,455.
64
5K1500 OEM Specification
12.14 Software Setting Preservation Feature Set When a device is enumerated, software will configure the device using Set Features and other commands. These software settings are often preserved across software reset but not necessarily across hardware reset. In Parallel ATA, only commanded hardware resets can occur, thus legacy software only reprograms settings that are cleared for the particular type of reset it has issued. In Serial ATA, COMRESET is equivalent to hard reset and a non-commanded COMRESET may occur if there is an asynchronous loss of signal. Since COMRESET is equivalent to hardware reset, in the case of an asynchronous loss of signal some software settings may be lost without legacy software knowledge. In order to avoid losing important software settings without legacy driver knowledge, the software settings preservation ensures that the value of important software settings is maintained across a COMRESET. Software settings preservation may be enabled or disabled using Set Features with a subcommand code of 06h. Software settings preservation is enabled by default.
12.14.1 Preserved software settings
If Software setting preservation is enabled, the following settings are preserved across COMRESET. Otherwise settings are cleared across COMRESET.

12.15 Native Command Queuing Native Command Queuing feature (Read / Write FPDMA Queued commands) is supported. Please refer to the Serial ATA II Specification about Native Command Queuing.
The host shall not issue a legacy ATA command while a native queued command is outstanding. Upon receiving a legacy ATA command while a native queued command is outstanding, the device aborts the command and halts command processing of outstanding native queued commands.
12.16 SMART Command Transport (SCT) SMART Command Transport (SCT) feature set is supported. The SMART Read Log and SMART Write Log commands or Read Log Ext and Write Log Ext commands are used to issue a command in this feature sets. Log page E0h is used to issue commands and return status. Log page E1h is used to transport data. Please refer to the section 8 SCT Command Transport in ATA8-ACS specification for more detail.
The following Action codes are supported.

12.17 Power-Up In Standby (PUIS) feature set The Power-Up In Standby (PUIS) feature set allows devices to be powered-up into the Standby power management state to minimize inrush current at power-up and to allow the host to sequence the spin-up of devices. This feature set may be enabled or disabled via the SET FEATURES command; Once this feature is enabled in a device, the device shall not disable the feature as a result of processing a power-on reset, a hardware reset, or a software reset. If power-up into Standby is enabled, the device shall remain in Standby until receipt of the first command that requires the device to access the media, except the IDENTIFY DEVICE command. The device implements this SET FEATURES subcommand, the fact that the feature is implemented is reported in the IDENTIFY DEVICE data. See Word 02 of “Table 58 Identify device information” on Page 91 for the definition.
If the device: a) Implements the Enable/disable Power-up in Standby subcommand; b) Has the PUIS feature set enabled; and c) receives an IDENTIFY DEVICE while the device is in the Standby power mode as a result of powering up in
that mode. Then the device shall respond to the IDENTIFY DEVICE command without spinning up the media. If the device is unable to return a complete response without accessing the media, then the device shall set word 0 bit 2 to one to indicate that the response is incomplete. At a minimum, word 0 and word 2 shall be correctly reported. Those fields that are not provided shall be filled with zeros. Once a device is able to return all data for an IDENTIFY DEVICE command, the device shall return all data for those commands until after processing the next power-on reset.

12.18 Early Drive Ready (EDR) function The Early Drive Ready (EDR) function is implemented. In this function, power on reset (POR) process is divided in two processes; POR1 and POR2. POR1 is the process for provide drive read operation; POR2 is the process for drive write operation. When EDR function is implemented, the drive returns Ready (Status: Error = 50:01) when POR1 is completed. POR2 is started by any of following condition. - Write type commands received - 2 seconds passed after drive ready - 500 milliseconds command interval POR2 is interrupted only by free fall sensor (FFS) or unload immediate (ULI) command interrupt. Other commands received while POR2 is running processed after POR2 is completed. After POR2 is interrupted by FFS or ULI, POR2 will be executed after FFS/ULI is resumed. All ATA commands are divided in two groups; read type and write type. Two ‘ready’ states are defined for the EDR function supported drive; Read Ready and Full Ready. Drive enters ‘Read Ready’ state when POR1 is completed, and enters ‘Full Ready’ state when POR2 is completed. While ‘Read Ready’ state, drive accepts and executes read type commands. Write type commands are accepted but POR2 is carried out before executing the command. Command Read / Write types are defined as follows. Soft reset and hard reset are treated as read type command.

13 Command Protocol The commands are grouped into different classes according to the protocols followed for command execution. The command classes with their associated protocols are defined below.
Please refer to Serial ATA Revision 3.0 (Section 11. device command layer protocol) about each protocol.
For all commands, the host must first check if BSY=1, and should proceed no further unless and until BSY=0. For all commands, the host must also wait for RDY=1 before proceeding.
A device must maintain either BSY=1 or DRQ=1 at all times until the command is completed. The INTRQ signal is used by the device to signal most, but not all, times when the BSY bit is changed from 1 to 0 during command execution.
A command shall only be interrupted with a COMRESET or software reset. The result of writing to the Command register while BSY=1 or DRQ=1 is unpredictable and may result in data corruption. A command should only be interrupted by a reset at times when the host thinks there may be a problem, such as a device that is no longer responding.
Interrupts are cleared when the host reads the Status Register, issues a reset, or writes to the Command Register.
“Table 144 Timeout Values” on Page 175 shows the device timeout values.
13.1 Data In Commands These commands are:
Device Configuration Identify Identify Device Read Buffer Read Log Ext Read Multiple Read Multiple Ext Read Sector(s) Read Sector(s) Ext S.M.A.R.T. Read Attribute Values S.M.A.R.T. Read Attribute Thresholds S.M.A.R.T. Read log sector
Execution includes the transfer of one or more 512 byte (>512 bytes on Read Long) sectors of data from the device to the host.
Note that the status data for a sector of data is available in the Status Register before the sector is transferred to the host.
If the device detects an invalid parameter, then it will abort the command by setting BSY=0, ERR=1, ABT=1.
If an error occurs, the device will set BSY=0, ERR=1, and DRQ=1. The device will then store the error status in the Error Register. The registers will contain the location of the sector in error. The erroneous location will be reported with CHS mode or LBA mode, the mode is decided by mode select bit (bit 6) of Device register on issuing the command.
13.2 Data Out Commands These commands are:
Device Configuration Set Download Microcode Format Track Security Disable Password Security Erase Unit Security Set Password Security Unlock Set Max Set Password Set Max Unlock S.M.A.R.T Write Log Sector
71
5K1500 OEM Specification
Write Buffer Write Log Ext Write Multiple Write Multiple Ext Write Multiple FUA Ext Write Sector(s) Write Sector(s) Ext
Execution includes the transfer of one or more 512 byte (>512 bytes on Write Long) sectors of data from the host to the device.
If the device detects an invalid parameter, then it will abort the command by setting BSY=0, ERR=1, ABT=1.
If an uncorrectable error occurs, the device will set BSY=0 and ERR=1, store the error status in the Error Register. The registers will contain the location of the sector in error. The errored location will be reported with CHS mode or LBA mode. The mode is decided by mode select bit (bit 6) of Device register on issuing the command.
13.3 Non-Data Commands These commands are:
Check Power Mode Device Configuration Freeze Lock Device Configuration Restore Execute Device Diagnostic Flush Cache Flush Cache Ext Format Unit Idle Idle Immediate Idle Immediate with Unload option Initialize Device Parameters Read Native Max Address Read Native Max Address Ext Read Verify Sector(s) Read Verify Sector(s) Ext Recalibrate Security Erase Prepare Security Freeze Lock Seek Sense Condition Set Features Set Max Address Set Max Address Ext Set Max Lock Set Max Freeze Lock Set Multiple Mode Sleep S.M.A.R.T. Disable Operations S.M.A.R.T. Enable/Disable Attribute Autosave S.M.A.R.T. Enable/Disable Automatic Off-line S.M.A.R.T. Enable Operations S.M.A.R.T. Execute Off-line Immediate S.M.A.R.T. Return Status S.M.A.R.T. Save Attribute Values Standby Standby Immediate Write Uncorrectable Ext
Execution of these commands involves no data transfer.
72
5K1500 OEM Specification
13.4 DMA Data Transfer Commands These commands are:
Read DMA Read DMA Ext Write DMA Write DMA Ext Write DMA FUA Ext
Initiation of the DMA transfer commands is identical to the Read Sector or Write Sector commands except that the host initializes the slave-DMA channel prior to issuing the command.
The DMA protocol allows high performance multi-tasking operating systems to eliminate processor overhead associated with PIO transfers.
Refer Functional Specification part for further details.
13.5 First-parity DMA Commands These commands are:
Read FPDMA Queued Write FPDMA Queued
Execution of this class of commands includes command queuing and the transfer of one or more blocks of data between the device and the host. The protocol is described in the section 11.14 “FPDMA Queued command protocol” of “Serial ATA revision 3.0”.

Table 48 Device Configuration Overlay Features register values
14.2.1 DEVICE CONFIGURATION RESTORE (subcommand C0h)
The DEVICE CONFIGURATION RESTORE command discard any setting previously made by a DEVICE CONFIGURATION SET command and return the content of the IDENTIFY DEVICE command response to the original settings as indicated by the data returned from the execution of a DEVICE CONFIGURATION IDENTIFY command.
14.2.2 DEVICE CONFIGURATION FREEZE LOCK (subcommand C1h)
The DEVICE CONFIGURATION FREEZE LOCK command prevents accidental modification of the Device Configuration Overlay settings. After successful execution of a DEVICE CONFIGURATION FREEZE LOCK command, all DEVICE CONFIGURATION SET, DEVICE CONFIGURATION FREEZE LOCK, DEVICE CONFIGURATION IDENTIFY, and DEVICE CONFIGURATION RESTORE commands are aborted by the device. The DEVICE CONFIGURATION FREEZE LOCK condition shall be cleared by a power-down. The DEVICE CONFIGURATION FREEZE LOCK condition shall not be cleared by COMRESET or software reset.

5K1500 OEM Specification
14.2.3 DEVICE CONFIGURATION IDENTIFY (subcommand C2h)
The DEVICE CONFIGURATION IDENTIFY command returns a 512 byte data structure via PIO data-in transfer. The content of this data structure indicates the selectable commands, modes, and feature sets that the device is capable of supporting. If a DEVICE CONFIGURATION SET command has been issued reducing the capabilities, the response to an IDENTIFY DEVICE or IDENTIFY PACKET DEVICE command will reflect the reduced set of capabilities, while the DEVICE CONFIGURATION IDENTIFY command will reflect the entire set of selectable capabilities.
The format of the Device Configuration Overlay data structure is shown on next page.
14.2.4 DEVICE CONFIGURATION SET (subcommand C3h)
The DEVICE CONFIGURATION SET command allows a device manufacturer or a personal computer system manufacturer to reduce the set of optional commands, modes, or feature sets supported by a device as indicated by a DEVICE CONFIGURATION IDENTIFY command. The DEVICE CONFIGURATION SET command transfers an overlay that modifies some of the bits set in words 63, 78, 79, 82, 83, 84, and 88 of the IDENTIFY DEVICE command response. When the bits in these words are cleared, the device no longer supports the indicated command, mode, or feature set. If a bit is set in the overlay transmitted by the device that is not set in the overlay received from a DEVICE CONFIGURATION IDENTIFY command, no action is taken for that bit.
The format of the overlay transmitted by the device is described in the table at next page. The restrictions on changing these bits are described in the text following that table. If any of the bit modification restrictions described are violated or any setting is changed with DEVICE CONFIGURATION SET command, the device shall return command aborted. At that case, error reason code is returned to sector count register, invalid word location is returned to LBA High register, and invalid bit location is returned to LBA Mid register. The Definition of error information is shown on the next page.

Table 51 Download Command (92h)
Output Parameters To The Device Feature Subcommand code.
03h : Download and save microcode with offsets. 07h : Download and save microcode. Other values are reserved.
Sector Count Lower byte of 16-bit sector count value to transfer from the host. LBA Low Higher byte of 16-bit sector count value to transfer from the host. LBA High/Mid Buffer offset (only used for Feature = 03h) This command enables the host to alter the device's microcode. The data transferred using the DOWNLOAD MICROCODE commands is vendor specific.
All transfers shall be an integer multiple of the sector size. The size of the data transfer is determined by the contents of the LBA Low and Sector Count registers. The LBA Low register is used to extend the Sector Count register to create a 16-bit sector count value. The LBA Low register is the most significant eight bits and the Sector Count register is the least significant eight bits.
ABT will be set to 1 in the Error Register if the value in the Feature register is neither 03h nor 07h, or the device is in Security Locked mode. When the reload of new microcode is requested in the data sent by the host for this Download command, UNC error will be set to 1 in the Error Register if the device fails to reload new microcode.
In reloading new microcode, when the spin-up of the device is disabled, the device spins down after reloading new microcode.
A Features register value of 03h indicates that the microcode will be transferred in one or more Download Microcode commands using the offset transfer method. The buffer offset value is starting location in the microcode file, which varies in 512 byte increments. It is defined by the LBA High and LBA Mid registers. The LBA High register is the most significant eight bits and the LBA Mid register is the least significant eight bits of the buffer offset value.
All microcode segments shall be sent to the device in sequence.
The device will abort the DOWNLOAD MICROCODE command and discard all previously downloaded microcode, if the current buffer offset is not equal to the sum of the previous DOWNLOAD MICROCODE command buffer offset and the previous sector count. The first DOWNLOAD MICROCODE command shall have a buffer offset of zero.
The new firmware becomes effective immediately after the transfer of the last data segment has completed.
When the device detects the last download microcode command for the firmware download the device will perform any device required verification and save the complete set of downloaded microcode.
83
5K1500 OEM Specification
If the device receives a command other than download microcode prior to the receipt of the last segment the new command is executed and all previously downloaded microcode is discarded.
If a software or hardware Reset is issued to the device before all of the microcode segments have been transferred to the device the device shall abandon all of the microcode segments received and process the Reset.

Output Parameters To The Device LBA Low In LBA mode, this register specifies LBA address bits 0 - 7 to be formatted. (L=1) LBA High/Mid The cylinder number of the track to be formatted. (L=0)
In LBA mode, this register specifies LBA address bits 8 - 15 (Mid), 16 - 23 (High) to be formatted. (L=1)
H The head number of the track to be formatted. (L=0) In LBA mode, this register specifies LBA address bits 24 - 27 to be formatted. (L=1)
Input Parameters From The Device LBA Low In LBA mode, this register specifies current LBA address bits 0-7. (L=1) LBA High/Mid In LBA mode, this register specifies current LBA address bits 8 - 15 (Mid), 16 - 23 (High)H In LBA mode, this register specifies current LBA address bits 24 - 27. (L=1) In LBA mode, this command formats a single logical track including the specified LBA.

Table 56 Format Unit Command (F7h)
The Format Unit command initializes all user data sectors after merging reassigned sector location into the defect information of the device and clearing the reassign information. Both new reassign information and new defect information are available right after this command completion, and are also used on next power on reset. Both previous information are erased from the device by this command.
Note that the Format Unit command initializes from LBA 0 to Native MAX LBA. Host MAX LBA set by Initialize Drive Parameter or Set MAX ADDRESS command is ignored. So the protected area by Set MAX ADDRESS commands is also initialized.
The security erase prepare command should be completed immediately prior to the Format Unit command. If the device receives a Format Unit command without a prior Security Erase Prepare command the device aborts the Format Unit command.
If Feature register is NOT 11h, the device returns Abort error to the host.
This command does not request to data transfer.
Output Parameters To The Device Feature Destination code for this command 11H Merge reassigned location into the defect information The execution time of this command depends on drive capacity. To determine command timeout value, Word 89 of Identify Device data should be referred.

Table 68 Idle Command (E3h/97h)
When the power save mode is Standby mode, the Idle command causes the device to enter performance Idle mode immediately, and set auto power down timeout parameter(standby timer). And then the timer starts counting down. When the device’s power save mode is already any idle mode, the device keep that mode.
When the Idle mode is entered, the device is spun up to operating speed. If the device is already spinning, the spin up sequence is not executed.
During Idle mode the device is spinning and ready to respond to host commands immediately.
Output Parameters To The Device
Sector Count Timeout Parameter. If zero, then the automatic power down sequence is disabled. If non-zero, then the automatic power down sequence is enabled, and the timeout interval is shown below:
Value Timeout
---------- -------------------------
0 Timer disabled
1-240 Value * 5
241-251 (Value-240) * 30 minutes
252 21 minutes
253 8 hours
254 Reserved
255 21 minutes 15 seconds
When the automatic power down sequence is enabled, the drive will enter Standby mode
automatically if the timeout interval expires with no drive access from the host. The timeout interval will be reinitialized if there is a drive access before the timeout interval expires.

Table 69 Idle Immediate Command (E1h/95h)
The Idle Immediate command causes the device to enter performance Idle mode.
The device is spun up to operating speed. If the device is already spinning, the spin up sequence is not executed.
During Idle mode the device is spinning and ready to respond to host commands immediately.
The Idle Immediate command will not affect the auto power down timeout parameter.
Unload Feature: The UNLOAD FEATURE of the IDLE IMMEDIATE command allows the host to immediately unload the heads. The device stops read look-ahead if it is in process. If the device is performing a write operation, the device suspends writing cached data onto the media as soon as possible. The data in the write cache is retained, and the device resumes writing the cached data onto the media after receiving a Software Reset, a Hardware Reset, or any new command except IDLE IMMEDIATE with UNLOAD FEATURE.

14.17.5 Phy Event Counter
Phy Event Counters are a feature to obtain more information about Phy level events that occur on the interface. The counter values are not retained across power cycles. The counter values are preserved across COMRESET and software resets.
14.17.5.1 Counter Reset Mechanisms There are 2 mechanisms by which the host can explicitly cause the Phy counters to be reset. The first mechanism is to issue a BIST Activate FIS to the drive. The second mechanism uses the Read Log Ext command. When the drive receives a Read Log Ext command for log page 11h and bit 0 in Feature register is set to one, the drive returns the current counter values for the command and then resets all Phy event counter values.
14.17.5.2 Counter Identifiers Each counter begins with a 16-bit identifier. The following table defines the counter value for each identifier.
For all counter descriptions, “transmitted” refers to items sent by the drive to the host and “received” refers to items received by the drive from the host.

Table 100 Security Erase Unit Command (F4h)
The Security Erase Unit command initializes all user data sectors, then disables the device lock function.
Note that the Security Erase Unit command initializes from LBA 0 to Native Max LBA. Host Max LBA set by Initialize Drive Parameter or Set Max Address command is ignored. So the protected area by Set Max Address command is also initialized.
This command requests to transfer a single sector data from the host including information specified in the following table.
If the password does not match then the device rejects the command with an Aborted error.
Word Description Control word bit 0 Identifier (1-Mater, 0-User) bit 1 Erase mode (1-Enhanced Erase, 0-Normal Erase)
00
bit 2-15 Reserved 01-16 Password (32 bytes) 17-255 Reserved
Table 101 Erase Unit Information
Identifier Zero indicates that the device should check the supplied password against the user password stored internally. One indicates that the device should check the given password against the master password stored internally.
The Security Erase Unit command erases all user data and disables the security mode feature (device lock function). So after completing this command, all user data will be initialized to zero with write operation. At this time, it is not verified with read operation whether the sector of data is initialized correctly. Also, the defective sector information and the reassigned sector information for the device are not updated. The security erase prepare command should be completed immediately prior to the Security Erase Unit command. If the device receives a Security Erase Unit command without a prior Security Erase Prepare command the device aborts the security erase unit command.
This command disables the security mode feature (device lock function), however the master password is still stored internally within the device and may be re-activated later when a new user password is set. If you execute this command on disabling the security mode feature (device lock function), the password sent by the host is NOT compared with the password stored in the device for both the Master Password and the User Password, and then the device only erases all user data.
The execution time of this command is set in Word 89 of Identify Device data information.
The execution time of this command is set in Word 90 of Identify Device data information.
In case of the FDE model, the execution time in Enhanced Erase mode is less than 1 minutes.

Table 103 Security Set Password Command (F1h)
The Security Set Password command enables security mode feature (device lock function), and sets the master password or the user password.
The security mode feature (device lock function) is enabled by this command, and the device is not locked immediately. The device is locked after next COMRESET with Software Setting Preservation disabled or power on reset. When the MASTER password is set by this command, the master password is registered internally, but the device is NOT locked after next power on reset.
This command requests a transfer of a single sector of data from the host including the information specified in the following table.
The data transferred controls the function of this command.
Word Description Control word bit 0 : Identifier (1-Mater, 0-User) bit 1-7 : Reserved bit 8 : Security level (1-Maximum, 0-High)

Table 104 Security Set Password Information
Identifier Zero indicates that the device should check the supplied password against the user password stored internally. One indicates that the device should check the given password against the master password stored internally.
Security Level Zero indicates High level, one indicates Maximum level. If the host sets High level and the password is forgotten, then the Master Password can be used to unlock the device. If the host sets Maximum level and the user password is forgotten, only an Security Erase Prepare/Security Unit command can unlock the device and all data will be lost.
Password The text of the password - all 32 bytes are always significant. Master Password Revision Code
The Revision Code field is set with Master password. If Identifier is User, the Revision Code is not set. The Revision Code field is returned in Identify Device word 92. The valid Revision Codes are 0001h to FFFeh. Default Master Password Revision Code is FFFeh. Value 0000h and FFFfh is reserved.

5K1500 OEM Specification
The setting of the Identifier and Security level bits interact as follows. Identifier=User / Security level = High The password supplied with the command will be saved as the new user password. The security mode feature (lock function) will be enabled from the next power on. The file may then be unlocked by either the user password or the previously set master password.
Identifier=Master / Security level = High This combination will set a master password but will NOT enable the security mode feature (lock function).
Identifier=User / Security level = Maximum The password supplied with the command will be saved as the new user password. The security mode feature (lock function) will be enabled from the next power on. The file may then be unlocked by only the user password. The master password previously set is still stored in the file but may NOT be used to unlock the device.
Identifier=Master / Security level = Maximum This combination will set a master password but will NOT enable the security mode feature (lock function).

Table 105 Security Unlock Command (F2h)
This command unlocks the password and causes the device to enter device unlock mode. If COMRESET with Software Setting Preservation disable or power on reset is done without executing the Security Disable Password command after this command is completed, the device will be in device lock mode. The password has not been changed yet.
The Security Unlock command requests to transfer a single sector of data from the host including information specified in the following table.
If the Identifier bit is set to master and the file is in high security mode then the password supplied will be compared with the stored master password. If the file is in maximum security mode then the security unlock will be rejected.
If the Identifier bit is set to user, then the file compares the supplied password with the stored user password.
If the password compare fails then the device returns an abort error to the host and decrements the unlock attempt counter. This counter is initially set to 5 and is decremented for each password mismatch. When this counter reaches zero then all password protected commands are rejected until a power off.
Word Description Control word bit 0 : Identifier (1-Master, 0-User)
00 bit 1-15 : Reserved
01-16 Password (32 bytes) 17-255 Reserved
Table 106 Security Unlock Information
Identifier Zero indicates that device regards Password as User Password. One indicates that device regards Password as Master Password.
The user can detect if the attempt to unlock the device has failed due to a mismatched password as this is the only reason that an abort error will be returned by the file AFTER the password information has been sent to the device. If an abort error is returned by the device BEFORE the password data has been sent to the file then another problem exists.

Table 110 Set Max Address Command (F9h)
The Set Max Address command overwrites the max LBA/CYL of HDD in a range of actual device capacities. The device receives this command, all accesses beyond that LBA/CYL are rejected with setting ABORT bit in status register. Identify device command and Identify device DMA command returns the LBA/CYL which is set via this command as a default value.
This command implement SET Max security extension commands as subcommands. But regardless of Feature register value, the case this command is immediately preceded by a Read Native Max Address command, it is interpreted as a Set Max Address command.
The Read Native Max Address command should be issued and completed immediately prior to issuing Set Max Address command. Otherwise this command is interpreted as a Set Max security extension command which is destinated by feature register. If Set Max security mode is in the Locked or Frozen, the Set Max Address command is aborted.
For more information, see “12.10.2 Set Max security extension commands” on Page 61.
In CHS mode, LBA High, LBA Mid specify the max cylinder number. The Head number of Device and LBA Low are ignored. The default value(See default CHS in Identify device information) is used for that.
In LBA mode, the Head number of Device, LBA High, LBA Mid and LBA Low specify the max LBA. This command sets this LBA as the max LBA of the device.
After a successful command completion, Identify Device response words (61:60) shall reflect the maximum address set with this command.
If the 48-bit Address feature set is supported, the value placed in Identify Device response words (103:100) shall be the same as the value placed in words (61:60). However, if the device contains greater than 268,435,455 sectors, the capacity addressable with 28-bit commands, and the address requested is 268,435,455, the max address shall be changed to the native maximum address, the value placed in words (61:60) shall be 268,435,455 and the value placed in words (103:100) shall be the native maximum address.
If a host protected area has been established by a Set Max Address Ext command, the device shall return command aborted.

Table 111 Set Max Address Ext Command (37h)
This command is immediately preceded by a Read Native Max Address Ext command.
This command overwrites the maximum number of Address of HDD in a range of actual device capacity. Once device receives this command, all accesses beyond that Address are rejected with setting ABORT bit in status register.
When the address requested is greater than 268,435,455, words (103:100) shall be modified to reflect the requested value, but words (61:60) shall not modified. When the address requested is equal to or less than 268,435,455, words (103:100) shall be modified to reflect the requested value, and words (61:60) shall also be modified.
If this command is not supported, the maximum value to be set exceeds the capacity of the device, a host protected area has been established by a Set Max Address command, the command is not immediately preceded by a Read Native Max Address Ext command, or the device is in the Set Max Locked or Set Max Frozen state, the device shall return command aborted.
The device returns the command aborted for a second non-volatile Set Max Address Ext command until next power on.

Table 114 S.M.A.R.T. Function Set Command (B0h)
The S.M.A.R.T. Function Set command provides access to Attribute Values, Attribute Thresholds and other low level subcommands that can be used for logging and reporting purposes and to accommodate special user needs. The S.M.A.R.T. Function Set command has several separate subcommands which are selectable via the device’s Features Register when the S.M.A.R.T. Function Set command is issued by the host.
14.41.1 S.M.A.R.T. Sub commands
In order to select a subcommand the host must write the subcommand code to the device’s Features Register before issuing the S.M.A.R.T. Function Set command. The subcommands and their respective codes are listed below.
Code Subcommand D0h S.M.A.R.T. Read Attribute Values D1h S.M.A.R.T. Read Attribute Thresholds D2h S.M.A.R.T. Enable/disable Attribute Autosave D3h S.M.A.R.T. Save Attribute Values D4h S.M.A.R.T. Execute Off-line Immediate D5h S.M.A.R.T. Read Log Sector D6h S.M.A.R.T. Write Log Sector D8h S.M.A.R.T. Enable Operations D9h S.M.A.R.T. Disable Operations Dah S.M.A.R.T. Return Status Dbh S.M.A.R.T. Enable/Disable Automatic Off-Line S.M.A.R.T. Read Attribute Values (Subcommand D0h) This subcommand returns the device’s Attribute Values to the host. Upon receipt of the S.M.A.R.T. Read Attribute Values subcommand from the host, the device saves any updated Attribute Values to the Attribute Data sectors, and then waits for the host to transfer the 512 bytes of Attribute Value information from the device.
S.M.A.R.T. Read Attribute Thresholds (Subcommand D1h) This subcommand returns the device’s Attribute Thresholds to the host. Upon receipt of the S.M.A.R.T. Read Attribute Thresholds subcommand from the host, the device reads the Attribute Thresholds from the Attribute Threshold sectors and then waits for the host to transfer the 512 bytes of Attribute Thresholds information from the device.
S.M.A.R.T. Enable/Disable Attribute Autosave (Subcommand D2h) This subcommand enables and disables the attribute autosave feature of the device. The S.M.A.R.T. Enable/Disable Attribute Autosave subcommand allows the device to automatically save its updated Attribute Values to the Attribute Data Sector at the timing of the first transition to Active idle mode after 30 minutes since the last saving of Attribute Values; this subcommand causes the autosave feature to be disabled. The state of the Attribute Autosave feature (either enabled or disabled) will be preserved by the device across power cycle.
144
5K1500 OEM Specification
A value of 00h written by the host into the device’s Sector Count Register before issuing the S.M.A.R.T. Enable/Disable Attribute Autosave subcommand will cause this feature to be disabled. Disabling this feature does not preclude the device from saving Attribute Values to the Attribute Data sectors during some other normal operation such as during a power-up or power-down.
A value of F1h written by the host into the device’s Sector Count Register before issuing the S.M.A.R.T. Enable/Disable Attribute Autosave subcommand will cause this feature to be enabled. Any other non-zero value written by the host into this register before issuing the S.M.A.R.T. Enable/Disable Attribute Autosave subcommand will not change the current Autosave status but the device will respond with the error code specified in “Table 128 S.M.A.R.T. Error Codes” on Page 158.
The S.M.A.R.T. Disable Operations subcommand disables the autosave feature along with the device’s S.M.A.R.T. operations.
Upon the receipt of the subcommand from the host the device enables or disables the Autosave feature.
S.M.A.R.T. Save Attribute Values (Subcommand D3h) This subcommand causes the device to immediately save any updated Attribute Values to the device’s Attribute Data sector regardless of the state of the Attribute Autosave feature. Upon receipt of the S.M.A.R.T. Save Attribute Values subcommand from the host, the device writes any updated Attribute Values to the Attribute Data sector.
S.M.A.R.T. Execute Off-line Immediate (Subcommand D4h) This subcommand causes the device to immediately initiate the set of activities that collect Attribute data in an off-line mode (off-line routine) or execute a self-test routine in either captive or off-line mode.
The LBA Low register shall be set to specify the operation to be executed.
LBA Low Operation to be executed 0 Execute S.M.A.R.T. off-line data collection routine immediately 1 Execute S.M.A.R.T. Short self-test routine immediately in off-line mode 2 Execute S.M.A.R.T. Extended self-test routine immediately in off-line mode 3 Reserved 4 Execute SMART Selective self-test routine immediately in off-line mode 127 Abort off-line mode self-test routine 128 Reserved 129 Execute S.M.A.R.T. Short self-test routine immediately in captive mode 130 Execute S.M.A.R.T. Extended self-test routine immediately in captive mode 131 Reserved 132 Execute SMART selective self-test routine immediately in captive mode Off-line mode: The device executes command completion before executing the specified routine. During execution of the routine the device will not set BSY nor clear DRDY. If the device is in the process of performing its routine and is interrupted by a new command from the host, the device will abort or suspend its routine and service the host within two seconds after receipt of the new command. After servicing the interrupting command, the device will resume its routine automatically or not start its routine depending on the interrupting command.
Captive mode: When executing self-test in captive mode, the device sets BSY to one and executes the specified self-test routine after receipt of the command. At the end of the routine, the device sets the execution result in the Self-test execution status byte and ATA registers as below and executes command completion.
Status Set ERR to one when self-test has failed Error Set ABRT to one when self-test has failed LBA Mid Set to F4h when self-test has failed LBA High Set to 2ch when self-test has failed SMART Selective self-test routine When the value in the LBA Low register is 4 or 132, the Selective self-test routine shall be performed. This self-test routine shall include the initial tests performed by the Extended self-test routine plus a selectable read scan. The host shall not write the Selective self-test log while the execution of a Selective self-test command is in progress.
The user may choose to do read scan only on specific areas of the media. To do this, user shall set the test spans desired in the Selective self-test log and set the flags in the Feature flags field of the Selective self-test log to indicate do not perform off-line scan. In this case, the test spans defined shall be read scanned in their entirety. The Selective self-test log is updated as the self-test proceeds indicating test progress. When all specified test spans have been completed, the test is terminated and the appropriate self-test execution status is reported in the S.M.A.R.T. READ DATA response depending on the occurrence of errors. The following figure shows an example of a Selective selftest definition with three test spans defined. In this example, the test terminates when all three test spans have been scanned.
145
5K1500 OEM Specification
Figure 9 Selective self-test test span example
After the scan of the selected spans described above, a user may wish to have the rest of media read scanned as an off-line scan. In this case, the user shall set the flag to enable off-line scan in addition to the other settings. If an error occurs during the scanning of the test spans, the error is reported in the self-test execution status in the S.M.A.R.T. READ DATA response and the off-line scan is not executed. When the test spans defined have been scanned, the device shall then set the offline scan pending and active flags in the Selective self-test log to one, the span under test to a value greater than five, the self-test execution status in the S.M.A.R.T. READ DATA response to 00h, set a value of 03h in the off-line data collection status in the S.M.A.R.T. READ DATA response and shall proceed to do an off-line read scan through all areas not included in the test spans. This off-line read scan shall completed as rapidly as possible, no pauses between block reads, and any errors encountered shall not be reported to the host. Instead error locations may be logged for future reallocation. If the device is powered-down before the off-line scan is completed, the off-line scan shall resume when the device is again powered up. From power-up, the resumption of the scan shall be delayed the time indicated in the Selective self-test pending time field in the Selective self-test log. During this delay time the pending flag shall be set to one and the active flag shall be set to zero in the Selective self-test log. Once the time expires, the active flag shall be set to one, and the off-line scan shall resume. When the entire media has been scanned, the off-line scan shall terminate, both the pending and active flags shall be cleared to zero, and the off-line data collection status in the S.M.A.R.T. READ DATA response shall be set to 02h indicating completion.
During execution of the Selective self-test, the self-test executions time byte in the Device S.M.A.R.T. Data Structure may be updated but the accuracy may not be exact because of the nature of the test span segments. For this reason, the time to complete off-line testing and the self-test polling times are not valid. Progress through the test spans is indicated in the selective self-test log.
A COMRESET or software reset shall abort the Selective self-test except when the pending bit is set to one in the Selective self-test log (see 14.41.7 Selective self-test log data structure). The receipt of a S.M.A.R.T. EXECUTE OFF-LINE IMMEDIATE command with 0fh, Abort off-line test routine, in the LBA Low register shall abort Selective self-test regardless of where the device is in the execution of the command. If a second self-test is issued while a selective self-test is in progress, the selective self-test is aborted and the newly requested self-test is executed.

5K1500 OEM Specification
S.M.A.R.T. Read Log Sector (Subcommand D5h) This command returns the specified log sector contents to the host.
The 512 bytes data are returned at a command and the Sector Count value shall be set to one. The LBA Low shall be set to specify the log sector address.

S.M.A.R.T. Write Log Sector (Subcommand D6h) This command writes 512 bytes data to the specified log sector.
The 512 bytes data are transferred at a command and the Sector Count value shall be set to one. The LBA Low shall be set to specify the log sector address (Table 115 Log sector addresses). If Read Only log sector is specified, the device returns ABRT error.
S.M.A.R.T. Enable Operations (Subcommand D8h) This subcommand enables access to all S.M.A.R.T. capabilities within the device. Prior to receipt of a S.M.A.R.T. Enable Operations subcommand, Attribute Values are neither monitored nor saved by the device. The state of S.M.A.R.T. (either enabled or disabled) will be preserved by the device across power cycles. Once enabled, the receipt of subsequent S.M.A.R.T. Enable Operations subcommands will not affect any of the Attribute Values.
Upon receipt of the S.M.A.R.T. Enable Operations subcommand from the host, the device enables S.M.A.R.T. capabilities and functions.
S.M.A.R.T. Disable Operations (Subcommand D9h) This subcommand disables all S.M.A.R.T.capabilities within the device including the device’s attribute autosave feature. After receipt of this subcommand the device disables all S.M.A.R.T. operations. Non self-preserved Attribute Values will no longer be monitored. The state of S.M.A.R.T. (either enabled or disabled) is preserved by the device across power cycles. Note that this subcommand does not preclude the device’s power mode attribute autosaving.
Upon receipt of the S.M.A.R.T. Disable Operations subcommand from the host, the device disables S.M.A.R.T. capabilities and functions.
After receipt of the device of the S.M.A.R.T. Disable Operations subcommand from the host, all other S.M.A.R.T. subcommands—with the exception of S.M.A.R.T. Enable Operations—are disabled, and invalid and will be aborted by the device (including the S.M.A.R.T. Disable Operations subcommand), returning the error code as specified in “Table 128 S.M.A.R.T. Error Codes” on Page 158.
Any Attribute Values accumulated and saved to volatile memory prior to receipt of the S.M.A.R.T. Disable Operations command will be preserved in the device’s Attribute Data Sectors. If the device is re-enabled, these Attribute Values will be updated, as needed, upon receipt of a S.M.A.R.T. Read Attribute Values or S.M.A.R.T. Save Attribute Values command.
S.M.A.R.T. Return Status (Subcommand Dah) This command is used to communicate the reliability status of the device to the host’s request. Upon receipt of the S.M.A.R.T. Return Status subcommand the device asserts BSY, saves any updated Attribute Values to the reserved sector and compares the updated Attribute Values to the Attribute Thresholds.
If the device does not detect a Threshold Exceeded Condition, or detects a Threshold Exceeded Condition but involving attributes are advisory, the device loads 4fh into the LBA Mid register, C2h into the LBA High register.
If the device detects a Threshold Exceeded Condition for pre-failure attributes, the device loads F4h into the LBA Mid register, 2ch into the LBA High register. Advisory attributes never result in negative reliability condition.

5K1500 OEM Specification
S.M.A.R.T. Enable/Disable Automatic Off-Line (Subcommand Dbh) This subcommand enables and disables the optional feature that cause the device to perform the set of off-line data collection activities that automatically collect attribute data in an off-line mode and then save this data to the device’s non-volatile memory. This subcommand may either cause the device to automatically initiate or resume performance of its off-line data collection activities or cause the automatic off-line data collection feature to be disabled. This subcommand also enables and disables the off-line read scanning feature that cause the device to perform the entire read scanning with defect reallocation as the part of the off-line data collection activities.
The Sector Count register shall be set to specify the feature to be enabled or disabled.
Sector Count Feature Description 00h Disable Automatic Off-line 01h Disable Off-line Read Scanning F8h Enable Automatic Off-line F9h Enable Off-line Read Scanning
A value of zero written by the host into the device’s Sector Count register before issuing this subcommand shall cause the automatic off-line data collection feature to be disabled. Disabling this feature does not preclude the device from saving attribute values to non-volatile memory during some other normal operation such as during a power-on or power-off sequence or during an error recovery sequence.
A value of one written by the host into the device’s Sector Count register before issuing this subcommand shall cause the off-line read scanning feature to be disabled. The Device does not perform the off-line read scanning at the off-line data collection activities which is initiated by the S.M.A.R.T. Execute Off-line Immediate (Subcommand D4h) or automatically if the off-line read scanning feature is disabled.
A value of F8h written by the host into the device’s Sector Count register before issuing this subcommand shall cause the automatic Off-line data collection feature to be enabled.
A value of F9 written by the host into the device’s Sector Count register before issuing this subcommand shall cause the off-line read scanning feature to be enabled. The Device perform the off-line read scanning at the off-line data collection activities which is initiated by the S.M.A.R.T. Execute Off-line Immediate(Subcommand D4h) even if the automatic off-line feature is disabled.
Any other non-zero value written by the host into this register before issuing this subcommand is vender specific and will not change the current Automatic Off-Line Data Collection and Off-line Read Scanning status, but device may respond with the error code specified in “Table 128 S.M.A.R.T. Error Codes” on Page 158.

Normalized Values: The device will perform conversion of the raw Attribute Values to transform them into normalized values, which the host can then compare with the Threshold values. A Threshold is the excursion limit for a normalized Attribute Value. In normalizing the raw data, the device will perform any necessary statistical validity checks to ensure that an instantaneous raw value is not improperly reflected in the normalized Attribute Value (i.e., one read error in the first 10 reads being interpreted as exceeding the read error rate threshold when the subsequent 1 billion reads all execute without error). The end points for the normalized values for all Attributes will be 1 (01h) at the low end, and 100 (64h) at the high end for the device. For Performance and Error Rate Attributes, values greater than 100 are also possible, up to a maximum value of 253 (Fdh).

Table 129 Standby Command (E2h/96h)
The Standby command causes the device to enter the Standby Mode immediately, and set auto power down timeout parameter(standby timer). When this command is issued, the device confirms the completion of the cached write commands. Then the device is spun down, but the interface remains active. If the device is already spun down, the spin down sequence is not executed. During the Standby mode the device will respond to commands, but there is a delay while waiting for the spindle to reach operating speed. The timer starts counting down when the device returns to Idle mode. Output Parameters To The Device
Sector Count Timeout Parameter. If zero, then the automatic power down sequence is disabled. If non-zero, then the automatic power down sequence is enabled, and the timeout interval is shown below:
Value Timeout
---------- -------------------------

241-251 (Value-240) * 30 minutes
252 21 minutes
253 8 hours
254 Reserved
255 21 minutes 15 seconds
When the automatic power down sequence is enabled, the drive will enter Standby mode
automatically if the timeout interval expires with no drive access from the host. The timeout interval will be reinitialized if there is a drive access before the timeout interval expires.

Table 143 Write Uncorrectable Ext Command (45h)
The Write Uncorrectable Ext command is used to cause the device to report an uncorrectable error when the target sector is subsequently read. As the logical sector is part of a larger (4KB) physical sector, then all the logical sectors within the same physical sector may report uncorrectable errors. When the Feature field (7:0) contains a value of 55h the Write Uncorrectable Ext command causes the device to indicate a failure when reads to any of the sectors that are contained in the physical block of the specified sector are performed. Theses sectors are referred to as “pseudo uncorrectable” sectors. In this case whenever a pseudo uncorrectable sector is accessed via a read command, the device performs normal error recovery and then set the UNC and ERR bits to indicate she sector is bad. When the feature field contains a value of Aah, the Write Uncorrectable Ext command causes the device to flag the specified sector as “flagged uncorrectable”. Flagging a logical sector as uncorrectable causes the device to indicate a failure when reads to specified sectors are performed. These sectors are referred to as “flagged uncorrectable” sectors. In this case whenever a “flagged uncorrectable” sector is accessed via a read command, the device sets the UNC and ERR bits without normal error recovery to indicate the sector is bad. If the Uncorrectable options are set to 55h, then sectors that have been made pseudo uncorrectable are listed as failed in the standard error logs when read back. If the Uncorrectable options are set to Aah, then the reading of pseudo uncorrectable sectors are not logged as an error in any standardized error logs. The pseudo uncorrectable or flagged uncorrectable status of a sector remains through a power cycle. If the device is unable to process a WRITE UNCORRECTABLE EXT command for any reason the device reports command aborted error.
